The Stellar Winds Atlas II: Black Hole Formation at Solar Metallicity
Amedeo Romagnolo, Floor S. Broekgaarden, Alex C. Gormaz-Matamala +7
The paper builds a comprehensive grid of stellar evolution models to compare 14 wind prescriptions and shows that black‑hole masses at solar metallicity are determined by whether a…
X-Shooting ULLYSES: Massive stars at low metallicity XV. On the metallicity dependence of B-supergiant mass-loss rates
O. Verhamme, J. O. Sundqvist, A. de Koter +21
Context. For stellar evolution models we rely on mass-loss rate prescriptions that show features that lack empirical confirmation, such as the bi-stability jump. This jump is an in…
New self-consistent theoretical descriptions for mass-loss rates of O-type stars
F. Figueroa-Tapia, J. A. Panei, M. Curé +5
Massive O-type stars lose a significant fraction of their mass through radiation-driven winds, a process that critically shapes their evolution and feedback into the interstellar m…
The Stellar Winds Atlas I: Current uncertainties in mass-loss rates
Amedeo Romagnolo, Floor S. Broekgaarden, Konstantinos Antoniadis +1
Stellar winds are a major source of uncertainty in understanding the life and deaths of massive stars. Across studies in the field, prescriptions for stellar winds differ substanti…
Revisiting the Evolutionary Status of Massive Stars at the central parsec of the Milky Way
A. C. Gormaz-Matamala, J. Cuadra, B. Kubátová +2
Massive stars and their winds have a large influence in their environment, e.g, determining the accretion rate on to the Galactic Centre (GC) super-massive black hole Sgr A*. The w…
Evolution of stars with 60 and 200 Msun: predictions for WNh stars in the Milky Way
Alex Camilo Gormaz-Matamala, Amedeo Romagnolo, Krzysztof Belczynski
We study in detail the evolution of two massive stars at solar metallicity (), by calculating their final masses, radial expansion, and chemical enrichment. We run evoluti…
